Rotational absolute magnetic encoder

13 September 2017 Test & Measurement

Vishay has introduced a new rotational magnetic position sensor that delivers accuracy comparable to Hall effect devices while offering higher reliability and better durability. The one-time programmable (OTP) Vishay Sfernice RAME027 provides accuracy of ±0,33 % at 25°C in a small 27 mm form factor. Typical applications will include military and industrial joysticks, electrical actuators, machine tools, textile manufacturing, milling and robotics.

“The robust capabilities and construction of the RAME027 make it the ideal solution for rough working conditions, including high vibration and shocks,” says Dirk Venter, field application engineer at Arrow Altech Distribution. Vishay can customise the RAME027 with customer-specified mechanical dimensions, output SSIs, accuracy and resolution levels, reinforcements, and protection features against EMC and ESD. The company can also provide redundant functions and an extended temperature range.

The RAME027 works from a 5 V (±0,25 V) supply and draws less than 20 mA at 5 V. It features a useful electrical angle of 360°, an analog output, 12-bit resolution, and works over a temperature range of -25°C to +85°C.
